On the FJO controller, you can be wide open throttle & in your window of operation, but until the tach swings past a preset rpms window, it will not engage the nitrous with the 1st gear lockout feature.

The other way is with a addition relay wired into the system. It's either operated by a button for like a 2 step or one on it's own. It's a wiring diagram for a trans brake setup will work for you if you want to go cheap. Wired button, relay, then your good to go.

As long as you hold the button, it won't spray, the second you release the party begins.

when we release the user interface for the wotbox you will be able to do that. next week i will draw up a diagram and install of how to use a relay in conjunction with the wotbox so that you wont spray on the 2 step

get the dyno tune digital tps switch, thats what i run, i have my nitrous cut off at 6100 so that i can no lift shift, and as for two step, the digital tps also has a 1st gear lock out feature.
OR if that doesnt satisfy you, you can run a little switch, like a switch that is used for WOT nitrous and mount it right in front of your clutch pedal so that when your not pressing the clutch, the switch is engaged, run the ground side of the nitrous and fuel solenoids through it, so that every time you press the clutch, the solenoids lose their grounds and shut off.

but i think is different because we use a device that cuts spark for several milliseconds, wot box, n then thats the part we fear.

get a wot box n wotshift while spraying to see if all is good.

Any way you can get this up by sat dude? planning on installing mine, and am currently running the dynotune digital window/wot switch.

My thinking was: Since its set on the dynotune switch to spray btw 3000-5900, when the WOT box activates at redline, when clutch is engaged. Shouldnt i in theory not be spraying by the since its going to be at 6K, after the window switch is closed.

Just been wondering also, as i have a 1st gear lockout and just havent played with it since ive only been spraying from 2nd gear pulls. Wanna hit the track soon and would like to use the 2-step. If im using the 1st gear lockout on the dynotune wouldnt it not matter than im WOT in 1st.

Just thinking out loud...maybe you can help.

yeah if you use the 1st gear lock out you should not have a problem WOT shifting from 1st to 2nd, just have the window switch cut out at 6 so you can WOT shift
